It is a well known fact that the trend of the dairy market has for some time been turning with increasing impetus toward universal use of paper or cardboard containers for milk and cream, these containers being generally of rectangular cross section. However, the means for safely and conveniently handling such containers have not kept pace with the popular adoption of the containers, so that an appreciable loss through damage of the latter is as yet considered unavoidable and therefore expected in the trade. In fact, the general and unlimited use of such milk containers is partly hampered and delayed for lack of proper facilities for safely handling the containers so that they will ultimately be delivered to the consumer intact and with full contents.

One weakness of the delivery cycl with respect to milk and cream containers is specifically that the boxes used heretofore have not been sufficiently strong to be durable nor designed to protect the containers effectively. Asid from the mentioned disadvantages remains the further serious and costly trouble of rapid deterioration of the boxes used, as they usually break apart in so short a time that their frequent replacement is an item of heavy expense with no remedy available on he market.

Having recognized the need for solving the very evident difficulties thus lying athwart the dairy business, we have now provided a box for holding milk containers of cardboard or paper, which will facilitate convenient and safe handling of such contianers without likelihood of the containers being injured or broken. If a carton or container should be injured or actually broken in the box, as is all too often the case in conventional boxes, loss of the product b leakage results. Even if injured or merely weakened in the box, the container is then in such condition that the subsequent handling of the same after removal from the box, may cause breakage of the container, principally by opening of the seams or joints near the bottom, whereby it will leak and thus lose the product.

One particular evil to which the milk boxes are exposed during transportation is a twisting action or distortion which conventional boxes are not rigid enough to withstand. Such distortion is especially harmful to milk containers, as they fit rather snugly in the boxes, which renders them subject to damage in that they are irresistibly caused to split open at the joints and scams, as already intimated Our box, by virtue of its special'oonstruction, features and mechanical design overcomes these disadvantages.

The box shown in Figures 1a, 1 to 9, d 14, comprises a metal bottom 23, having a centrally arranged raised portion 2| formed therein. This raised portion supports one or more of the milk containers, cartons, or bottles in raised position so that their tops project visibly above the other containers whereby they may be conveniently removed, rendering the subsequent removal of the remaining containers easy. This bottom 20 has inclined portions 22, extending downwardly in a longitudinal direction toward the opposite ends of the bottom. The bottom 20 has a downwardly projecting rib 23, which is rectangular and is arranged near the marginal edges of the bottom, and spaced inwardly therefrom. Thi rectangular rib stiffens the bottom and will fit into the open end of a companion box so that the boxes may be stacked. The rib 23 is provided with drain openings 24 and the rib 23 has depending hollow domes 25 formed thereon. The box slides upon these domes, in use, thus taking the wear off of the rib 23, and retaining the drain openings 24 uncovered. The bottom 26 has horizontal longitudinal extensions 26 and these horizontal extensions carry upstanding vertical longitudinal flanges 21.

Formed integral with the metal bottom 20 are metal ends 28, vertically arranged and disposed at right angles to the bottom. The ends of the rib 23 are spaced inwardly from the ends or end plates 28. Each end 28 isstifiened and reinforced by an outwardly bulging rib 29, which is rectangular, and carries outwardly bulging diagonal ribs 3|] at its corners. The rectangular rib 29 affords a space 33' which may be used as a name plate or the like. At its vertical edges, each end 28 is formed into vertical channels or sockets 3 I. Each socket is generally U-shaped in horizontal cross section and includes a wide inner side 32, a narrow outer side 33 and an end 34. Each outer side 33 has its free end bent inwardly to provide a locking tongue 35, disposed at right angles thereto. The channels 3| are open at their tops and bottoms.

Each end is extended at its top and bent outwardly and downwardly, providing a wide inclined plate 36, the free end of which is rolled into a cylindrical sleeve 37, the outer face of which is substantially flush with the outer face of the end 34. The plate 36 and associated elements form a handle construction. The plate 36 covers the fingers, protectin them when the user passes the fingers beneath the handle construction, in lifting the box.

In Figure 14, is shown a sheet metal blank from which the bottom ends and associated elements are formed. In this figure, the bottom 20 is bent upon longitudinal lines 38 to form the inclined portions 22 and upon lines 38' to form the longitudinal extensions 26, and these extensions are bent upon lines 39 to form the flanges 21. The rib 23 is disposed between the lines 38 and 38'. The ends 28 are carried by the bottom 20 and are formed by bending the bottom upon the transverse lines 40. At their vertical edges, the ends 28 carry the channels 3|, formed by bending the metal upon lines 4|, 42, and 43, forming the inner sides 32, outer sides 33 and ends 34. The blank has transverse folding lines 35, providing the tongues 35. The blank has transverse slits 43' terminating at the line 38. The channels 3| are separate from the extensions 26 and flanges 27. At their tops, the ends 28 are bent upon lines 44, to form the inclined wide plates 36, the free ends of which are rolled into the sleeves 31. These plates are separate from the channels 3|, are arranged between them, and contact therewith.

The sides 45 of the box are formed of wood. This reduces the weight of the box and eliminates undue noise, in handling. Each side is preferthe boards 46.

This feature .-provides." handles of sufficient strength, to withstand'thezpullithereon when the boxes are stacked-and theh'andle of the lower- I most box is pulled-for raising,:tipping,xorcarrying the stacked boxes. Rivets 54 extendthrough the sides 32 and '33' and th'ei upper boardsAB, near their lower edges, and rivets-"555 t=extend:.thr.ough the sides 32 and 33'and therlowenboardst near their lower edges,- inr absimilarwmanner.*to2the rivets 54.

In Figure 26, is shown a slight modification of the handle construction. Inl. this figure, the plate 36, corresponding to-the :plate" 36; is vertically curved and extends downwardlyyas shown. The same sleeve 31 and-connectingelement or tube 52 is used. This curved'plate 36.-..and: sleeve have clamping engagement with thesidesof the channels 3|. The elements 32 may be a solid rod instead of a tube. All other parts of the box remain identical with'thcse .before'shown and described.

In the second form o'f'the invention, shown in- Figures 15 to 24, the metal-bottom 20 is omitted. Formed integral with'the lower edgesof the ends 28' are metal bottom section's'55, see' more particularly Figure 18a. 'These metal bottom sections are provided at their outeredges with transverse. inwardly facingchanneIs5'IQ-the"cuter ends of which'extend'beneaththe sides' '32 a'nd'33 of the channels 3|.

The'transverse ribs 58 are spaced inwardly sufiicientlyfrom the inner faces of the ends 2%, andtheir ends are spaced inwardly fromithe inner faces of the lower side boards is so that the ribs 58 may enter the upper end of a companion box, wherebythe boxes may bestacked, Figure 22. 'All other parts of the box remain identical with those shown and describediin connection with'the first form of the invention.

As a further modification "of the invention,

2 Figures 10 and 11, metal ends 28 are substituted e for the metal ends'28' which are shown in Figures .15Lto 13. The top edges oi theends 28 are rolled into heads 5%. The tubes 52 arepased through 2. the openings 49, 55, and 5|, Figure 11, andserve .to connect the channels 3|.

The sleeves 3'! and plates 35 are omitted. All other parts of the ends 23 remain identical with the ends 28' shown and described in Figures 15 to 24.

In Figures 12 and 13, we have shown a further "modification of the invention. The numeral 28 designates metal ends,.corresponding to the metal ends 28. The metal'ends28 are slit vertically as shown at and the lower portions of the ends 28 are bent outwardly, forming an upper inclined portion 66 and lower vertical portions 61.

vThe portions fitand 6'5 are rigidly secured to the channels 3! by solder orthe like.

This aiTords suiiicient finger space beneath the sleeves 31.

.' All'other parts of the ends and box remain identical with those shown and described in connection with the first 'formof the invention as shown in Figures 1 to 9.

In'Figure 25, a slight modification of the box which is shown in Figure 23, is provided. In 'Figiwe 25, the lower side board 46 upon each side of the box contacts with the upper face of the bottom board 60. This is rendered possible by. a

' notch '59 cut in the lower edge 68 of the bottom board 46. The side board 145 and bottom board "66 may be secured together by nails or the like, if desired.

A further modification of the box is.shown .in Figures 2'7 to 29.. In these figures,-the numeral 28C designates metal ends, provided at theirvertical edges with vertical channels .3 l=. .,.corr.esponding to the channels 13 I'IFigure .1A. ...These.channels 3 l project outwardly beyond the outer faces ,of the ends ;Z.8,C These ch nnels ".rec iveazside boards 46', heldtherein by rivets 413;; The; ends 28C are provided at their top edges withinclined plates 36%, corresponding to. the plate;.36, Figure 7, and the plates 36 are provided with sleeves 3'I receivingtubes 52 corresponding. with the tubes 52. These tubes 52 clamp theinner sides of the channels. 3| against the plate 36 and the sleeve 3%. The ends 280 do not havethe horizontal channels 51, Figure 23. Each end cone tinues straight to its lower edge, and has lugs stamped therefrom and bent inwardly to assume a horizontal position and arranged upon the inner side of the end 280. The lugs Hi engage the upper surface of a bottom board 60A, and rivets H pass through these lugs, the bottom board 60A and a bottom extension 72. This bottom extension is formed integral with the end 28C and is bent at right angles thereto and extends upon the inner face of the end 280. Horizontal diagonal hollows-- stiffening ribs or gussets 73 are stamped from the inner sides of the channels 3| and the ends 28C, and serve to render the unit rigid. These ribs or gussets are disposed upon the outer face of the side 28C. While the box sides are shown and described as made of wood, this is not intended to form any necessary feature of the invention, as they may be made of any other suitable material, suchas various non-metallic compositions, press board or even plastics, if desired. On the other hand, the handle member at the ends of the box is shown hollow in the form of a tube, which is, of course the preferred form, but a solid rod of smaller diameter but of the same tensile strength could be used. Such a rod is obviously too thin to form a convenient handle and is preferably built up to form a comfortable grip by having a tube or sleeve mounted thereon, which is even' true of the inner tube shown in several of the views, although the sleeve in most cases is formed" of the projecting upper portion of the metal ends of the box projecting out to the handle tube and surrounding the same as a sleeve.

It is to be understood that the forms of our. invention herewith shown and described are to" be taken as preferred examples of the same, and that various changes in the shape, size, and arrangements of parts may be resorted to, without departing from the spirit of our invention, or the scope of the subjoined claims.
